Huawei Exam H31-161 Topic 1 Question 89 Discussion

Actual exam question for Huawei's H31-161 exam

Question #: 89
Topic #: 1

On a city's dual-plane bearer network, PE1-A and PE1-B are two PEs in different planes of the city.

Three CEs are on the same VPN. The OSPF is used to exchange VPN route information between CE

1 and PE1-A and between CE 2 and PE1-B. The default route leading to PE1-A is configured on CE

3, and a static route leading to CE 3 is configured on PE1-

AThe static route is imported to the OSPF,
and the OSPF route is imported to the VPN instance of the BGP. The MP-IBGP neighbor relationship
is established among the PEs. Subinterfaces are enabled in the links between PEs and are bound
to the same VPN to exchange VPN route information between PEs. How many routes on PE1-B can reach CE 3?

AOnly one (The route leading to CE 3 is learned based on the IBGP neighbor relationship between
PEs. The other route is filtered out by OSPF loopback detection.)

BTwo (One route is learned based on the IBGP neighbor relationship between PEs, and the other
one is the OSPF category-5 route.)

CNo route

DOnly the OSPF category-5 route can reach CE 3.

I'm gonna go with C. No route? That would be a real plot twist! Although, I hear the exam writers have a twisted sense of humor, so who knows.

I'm not so sure about that, maybe it's B) Two. It seems like there could be multiple routes to reach CE 3.

I agree with A. The OSPF route should be filtered out by the OSPF loopback detection, so there should only be one route to CE 3 on PE1-B.

I agree with you, Alaine. The static route is imported to the OSPF, so only one route on PE1-B can reach CE 3.

The correct answer is B. There are two routes to CE 3 on PE1-B, one learned through IBGP and the other through OSPF. The OSPF route is a category-5 route, which means it's a default route.
